Galerkin approximations for nonlinear evolution inclusions
Shouchuan Hu, Nikolaos S. Papageorgiou · Czech digital mathematics library · 1994
In this paper we study the convergence properties of the Galerkin approxima- tions to a nonlinear, nonautonomous evolution inclusion and use them to determine the structural properties of the solution set and establish the existence of periodic solutions. An example of a multivalued parabolic p.d.e. is also worked out in detail. In this paper we study the properties of the
